MrRissso [65]

Answer:

a. The number of neutrons in the nucleus

Explanation:

Having more protons or electrons would change the charge of the atom making it an ion. Neutrons have no charge so the overall charge of the atom is not affected; neutrons also have a relative mass of 1 which is why there are different isotopes.

Hope this helps!

If 5.48 g of CuNO3 is dissolved in water to make a 0.840 M solution, what is the volume of the solution in milliliters?
Ainat [17]

Answer:

34.8 mL

Explanation:

First we <u>convert 5.48 g of CuNO₃ into moles</u>, using its<em> molar mass</em>:

  • 5.48 g CuNO₃ ÷ 187.56 g/mol = 0.0292 mol

Now we can <u>calculate the volume of the solution</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • 0.840 M = 0.0292 mol / liters
  • liters = 0.0348 L

Finally we <u>convert L into mL</u>:

  • 0.0348 L * 1000 = 34.8 mL

John has a solution. It turns yellow when he adds red cabbage juice. Predict what colour the solution would turn if he added hib
FrozenT [24]

As the solution turns yellow when re cabbage juice indicator  is added it implies that its base solution so the color of the  solution when hibiscus flower juice added is dark grey to green.

when hibiscus indicator added Anywhere from dark pink to pale pink usually indicates an acid, while dark gray to green colors usually indicate a base.

Dark blue should be the color of  red cabbage indicator. The cabbage indicator's color will shift to red or pink if the solution is an acid, and to green or yellow if the solution is a base. In the event that the test solution is neutral, it will stay purple or blue
